Analogue Solutions Eurorack VCO 6HP Module - New!

New Module - ships with a power cable and mounting screws!

The VCO 6HP is one of the newest offerings from Analogue Solutions. This slim VCO is designed to give you maximum raw analogue power without taking too much real estate in your case or rack. The range is divine and can go down enough to be used as a LFO.

Voltage Controlled Oscillators (VCOs) in general

The VCO or signal generator, commonly found on most music synthesizers consist of an exponential amplifier, a resetable integrator and waveshaping circuitry. ‘Voltage Controlled Oscillator’ means an oscillator whose frequency can be controlled by an external voltage.

A VCO is responisble for the pitch of a sound and its basic timbre. Most VCOs will offer a variety of wave forms. Some VCOs offer the facility to alter the pulse width of a square wave either manually or with a voltage (pulse width modulation).

Controls In Detail

Tune

The VCO has a wide ranging tune control. Turning Tune alters the basic pitch of the oscillator.

Pulse Width

You can alter the pulse width (duty cycle) of the square wave. Turning this gives a sound similar to chorusing. In the centre position a square wave is produced.

Square Level

This sets the output volume of the square waveform output.

Sockets in Detail

CV in

This socket is the pitch CV control input and is used to control the pitch of the oscillator.

PW

This is a pulse width control CV input. Use a -12 to +12V voltage in this socket to alter the pulse width of the oscillator square wave.


Sawtooth Out

This is the audio output for the sawtooth waveform.

Square Out

This is the audio output for the square waveform. Its level is affected by the square level pot.
